Abstract (en)

Thermoplastic compositions include: (a) from about 10 wt. % to 60 wt. % of a first polyphenylene oxide PPO; (b) from about 0.5 wt. % to about 10 wt. % of a second PPO with low degree of polymerization and a viscosity between 0.1 dl/g and 0.3 dl/g; (c) from about 0.5 wt. % to about 10 wt. % of a general purpose polystyrene GPPS, (d) from about 0.5 wt% to about 10 wt% of an impact modifier; and (e) from about 30 wt. % to about 70 wt. % of an inorganic ceramic filler. A ratio of the first PPO and the second PPO to polystyrene is from 1:1 to 6:1. The combined weight percent value of all components does not exceed 100 wt. %, and all weight percent values are based on the total weight of the composition.
